Why Speed Matters

A slow website loses visitors. Studies show 53% of users leave if a page takes more than 3 seconds to load. Google uses page speed as a ranking factor. Fast sites convert better and rank higher.

Image Optimization

Images are the main cause of slow websites. Here's how to fix that:

• Use modern formats: WebP and AVIF are 25-50% smaller than JPEG/PNG.
• Resize images: Don't upload a 4000px image if you only display it at 800px.
• Compress: Tools like TinyPNG or Squoosh reduce file size without visible quality loss.
• Lazy load: Load images only when users scroll to them.

Clean Code

Minify your CSS and JavaScript files. Remove unused code. Combine files where possible. Every kilobyte counts.

Inline critical CSS for above-the-fold content. Defer non-essential scripts. Avoid render-blocking resources.

Caching

Browser caching stores files locally so returning visitors don't re-download everything. Set proper cache headers for static assets like images, CSS, and JavaScript.

CDN (Content Delivery Network)

A CDN serves your site from servers closest to your visitors. Someone in Tokyo shouldn't wait for data from a server in New York. CDNs reduce latency and improve load times globally.
